Evaluation on effectiveness of individual lingual orthodontics and labial straight wire orthodontics by X-ray cephalometrics
摘要
Abstract
Objective To compare the X-ray cephalometric results of teeth and skeleton relationship between individual lingual orthodontic and labial straight wire orthodontics,and to provide reliable theoretical foundation for selecting orthodontic system in clinic. Methods The general conditions of the patients, classification of malocclusion,severity of denture crowding and orthodontic design were used as the selection criteria. Thirty familiar adult patients with malocclusion in clinic were divided into two groups randomly:individual lingual orthodontics group (A group)and labial straight wire orthodontics group (B group),15 cases in each group.X-ray cephalometrics were taken using Steiner and Tweed cephalometrics analysis,the results of analysis were compared between pre-treatment and post-treatment in two groups respectively, and the course of treatment in two groups was compared,too.The difference of treatment effect and course of treatment between two different orthodontic systems was evaluated.Results The relationship of first molar and canine of the patients in two groups was neutral relationship,overbite and overjet of anterior teeth was shallow,the teeth arrangement was orderly and no space was left after treatment.There was no statistically significant difference (P>0.05)between two groups in each measured values detected by Steiner Analysis after orthodontic treatment;there was no statistically significant difference (P>0.05)between two groups in each measured value detected by Tweed Analysis after orthodontic treatment;and there was no statistical significance (P>0.05 )in the D-values of Steiner Analysis and Tweed Analysis between two groups before and after treatment.The duration of treatment of the patients in two groups had no significant difference (P>0.05).Conclusion Both individual lingual orthodontics and labial straight wire orthodontics could obtain well teeth arrangement and occluding relationship and achieve satisfying clinical orthodontic outcome.关键词
